Nucleus Term Papers Samples For Students

- Heterogeneous nuclear ribonucleoproteins is a protein that comprises of RNA binding proteins. It is a complex made up of RNA & proteins that is characterized by binding of premRNA. This occurs in the nucleus during the transcription and post transcriptional stages of preMRNA. The protein has different roles which include; prevent formation of secondary structures by preventing folding of pre-mRNA, inhibit the interaction with other proteins, usually has a link with the splicing apparatus and transportation of the mRNA away from the nucleus. This type of protein is a multidomain protein with multiple RNA binding proteins. RNA recognition Motif which is the commonest ...

The periodic table of elements, by far, stands among the most notable discoveries in the history of chemistry. Nowadays, probably everyone who has ever heard about chemistry heard about the periodic table of elements. Its implications on the scientific world are so enormous that it has even leaked out to the general public and have become associated with the chemistry itself. This is not surprising considering the scientific strength of this instrument. Using the periodic table, many characteristic properties of the elements can be predicted and many phenomena can be explained. This discovery put so much scientific knowledge together, ...

Introduction

This is a hereditary disease that has slow brain striatum atrophy (Gil and Rego). For several years, a Huntington’s disease patient may go through unrestrained movements, mental impairment and behavioral commotions. Finally, Huntington’s disease patients get totally reliant on a caregiver. The disease is an autosomal dominant condition that affects the equally two genders.

Statistics

The statistics of the Huntington’s disease indicate that out of 100,000 individuals globally, 5 to 10 will have the condition. The disease can attack males and females of every ethnic background (World Health Organization). It is prevalent globally, but, there are geographic regions where ...

Introduction

Unstable nuclei give rise to radioactive isotopes. Although there is a general belief that these isotopes are because of human activities quite a number occur naturally. Most of the radiations that we receive on earth have natural sources. The cosmic rays originate from space and other radioactive isotopes and we expose ourselves to daily. The most significant aspects of these radiations are their ability to transmit energy in terms of waves. The various forms of radiations include the visible light, radio waves and microwaves, which do not have to carry with them enough energy to ionize. Ionizing radiations are the ones, ...

Introduction:

The report seeks to explore the production and utilization of nuclear energy, a form of energy that is produced through a series of chemical reactions involving the atomic nuclei. In 1896, three scientists, Henrie Becquerel, Pierre Currie and Marie Curie, discovered the radioactivity in uranium salts and further pursued the experiments, and they separated radium, the highly radioactive component (Healey 37).
With advanced research, the atom came to be well defined. The terms alpha, beta and gamma decay, came into existence; that is, the release of energy when the nucleus releases neutrons and electrons in the form of electromagnetic radiation. ...

The discovery of DNA as the genetic material was one of the landmark events in the field of biology. By confirming DNA as the genetic material scientists made a huge leap that has advanced the cause of medical science to a great degree. While discussing the discovery of DNA as the genetic material, we mostly speak of Friedrich Miescher (1871), the man who discovered DNA. After the discovery of DNA a significant number of studies were conducted that proved DNA as the genetic material. Then Griffith, (1928) conducted studies on bacterial transformation and indicated that genetic information can be transferred from one ...
